HONGYE SILICONE’s Tough liquid silicone Compound is a high-strength two-component Addition Curing Silicone, specialized for high-wear, heavy-duty mould manufacturing. As a national high-tech enterprise with standardized production and one-stop solutions, this tough silicone compound is FDA and RoHS certified, non-toxic, odorless, and easy to operate, featuring exceptional tensile strength, tear resistance, and long service life. It caters to global B2B purchasers seeking durable mould materials, supporting industrial, craft, and precision scenarios, flexible customization, and mass production, helping reduce mould replacement frequency and lower long-term production costs.
Product Overview
Our Tough Liquid Silicone Compound is a premium RTV 2 Silicone Rubber, composed of high-purity flowable Part A (base rubber) and Part B (curing agent), adopting advanced addition curing technology. Tailored for toughness and durability, it supports both room-temperature and heat curing with simple operation, achieving shrink-free deep curing without thickness limits and producing no toxic by-products. Unlike ordinary Mold Making Silicone with poor wear resistance and short service life, it solves the pain points of frequent mould replacement, high maintenance costs, and unstable performance, making it the trusted choice for global B2B purchasers in high-demand industrial and craft fields.

Product Features & Advantages
2. Shrink-Free Deep Curing: No thickness limits, volume stability during curing, ensuring moulds retain shape and precision, reducing production defects and rework costs.
3. Food-Grade Safety: FDA and RoHS certified, non-toxic, odorless, no harmful by-products, suitable for food-contact moulds and high-standard industrial scenarios.
4. Long Service Life: Supports 110~130 mold cycles, 40% longer than ordinary mould silicone, significantly reducing mould replacement costs and production downtime.
5. Easy Operation & Customization: 1:1 mix ratio, simple operation; hardness, operating time, curing time, and color can be tailored to diverse tough mould requirements.
6. Stable Batch Quality: Standardized production ensures consistent toughness and performance (error ≤2%), avoiding quality fluctuations in mass production.
How to Use (Step-by-Step for Tough Mould Making)
1. Mix Part A and Part B of the tough liquid silicone compound in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free.
2. Perform vacuum degassing for 2~5 minutes; adjust time based on viscosity, weight, and vacuum intensity to eliminate bubbles and avoid mould defects.
3. Pour the degassed silicone into mould masters, leveraging good fluidity to fill all details and gaps, even for large or complex industrial moulds.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing to meet tight production schedules.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, and use within 10 months; avoid contact with sulfur-containing materials.
Application Scenarios
Our Tough Liquid Silicone Compound is widely used in global high-demand mould manufacturing, including heavy-duty concrete/cultural stone moulds, metal crafts, alloy car accessories, high-wear food moulds, epoxy resin/polyester resin moulds, and precision handboard models. It brings tangible value: reducing mould replacement costs by 45%+, improving production efficiency by 30%, ensuring stable mould quality under heavy use, and supporting mass production, helping B2B purchasers gain competitive advantages in the high-wear mould market.
